Re: separating zinc and copperIf I had no trouble looking up on the Internet how to separate Zn from Cu, why would professional engineers have any issues?
In regards to Serbia and their Timok project, Serbia is thrilled to have a Western co create jobs, where the unemployment runs close to 25%. The work force is well educated, and the government is very welcoming to foreign investment.
Serbia has been waiting for years to be accepted into the European Union, and so far been ignored. Serbia has been bombed by the Americans in the last war, so there is no love lost there. Serbian politicians have been lately warming up to Russia because it has been friendly, and showing Serbia some respect, but there is no desire on its part to become a Russian satelite.
Nevsun is pretty safe in that part of Europe.
